PRGTECTIVE OVERSHOE.

Specification of Letters Patent.

Patented Jan. 19. 1915.

.To all whom. it may concern Be it known that I, O'rro P. vKoEBEL, a citizen of the United $tates, residing in the city of St. Louis and State of Missouri, have invented new and useful Improvements in Protective Overshoes, of which the following is a specification.

This invention relates to protective overshoes or sandals.

It has for its principal objects the production of a device for protecting the sole and forepart of a shoe which is subjected to rough usage, and also for preventing injury to a workmans foot when working in and about a place where the shoe is liable to be burned, out or punctured; to produce a de vice of simple and inexpensive construction which can be readily applied to a shoe without taking materially from the flexibility of the latter or causing discomfort to the wearer; and to attain certain advantages which will hereinafter more fully appear.

In the accompanying drawing,Figure 1 is a plan view of a sandal made according to the invention; and Fig. 2 is a view partly in longitudinal section and partly in side elevation, showing the device applied to a shoe.

In the particular construction illustrated in the drawing, the sandal comprises a plate portion 1 which is adapted to cover the sole of the shoe and extends well up under the arch but terminates some distance short of the heel. The plate is preferably shaped so as1 to conform to the surface contour of the so e.

The plate 1 is provided on opposite sides with upstanding marginal flanges 2, while the front portion thereof is flanged upward and inward so as to overhang the toe of the shoe, as at 3, said portion 3 merging with the side flanges 2. The rear portion of the plate 1 is turned down, as at 4, and is perforated to receive a coupling bolt '5. This coupling bolt extends through a centrally perforated cross bar or plate 6, to the ends of which are attached the end portions of a wire loop 7, which latter is adapted to fit over the heel of the shoe. Preferably the cross plate 6 and heel loop 7 are connected flexibly or hingedly. As shown, the heel loop 7 is provided with eyes 8 at its ends, which portions are engaged in perforations provided there for in the cross plate 6. A nut 9 is provided on the coupling bolt 5 so as to be tightened provided with pointed projections 10 which take into the edge of the sole; and the heel loop 7 is provided with similar projections 11, which likewise engage the heel of the 5 Obviously, also, the bottom of the" shoe.

sole plate is provided with projections 12,2

or it may be otherwise roughened to prevent slipping.

In practice the side flanges 2 may be extended up only a distance suflicient to cover the sole, or some distance above the sole, as may be desirable. By carrying the portion 4 of the sole plate well up under the arch, as shown, the device serves as an arch support; while the coupling arrangement between the heel loop and the forepart of the device is such that there is sufficient flexibility so as not to materially affect the flexible. quality of the shoe on which the device is use I The forepart of the sandal may be made of metal, pressed fiber, or other suitable ma- 'terial, and it may or may not be lined with some soft material, as desired.

Obviously the device admits of considerable modification without departing from the spirit of the invention. Therefore I do not wish to be limited to the specific construction and arrangement shown.

I claim:

1. A protective sandal for shoes comprising a sole plate having upstanding side flanges and a toe flange, a heel loop, and a cross member connected at its ends'to the ends of the loop, said cross member having a perforation, a coupling bolt secured to said sole plate and extending through said perforation in said cross'member, and a nut on said coupling bolt arranged to be tightened against said cross member so as to draw said heel loop and said sole plate toward each other.

2. A protective sandal for shoes compris ing a sole plate having upstanding side flanges and a toe flange, the rear portion of said sole plate extending upward under the arch of the shoe, and terminating in a downturned flange, a coupling bolt secured to said down-turned flange, a heel loop, and a cross member connected at its ends to the ends of the loop, said cross member having a perforation, said coupling bolt being arranged to nected at its ends to the ends of the loop,

and an adjustable coupling device having a swivel connection with said cross member and said sole plate and arranged to draw said heel loop and said sole plate toward each other.

In testimony whereof, I have hereunto set my hand in presence of two subscribing Wit;
